Frequently Asked Questions

Why use a singleturn optical Hiperface encoder with 128 signal periods on this motor?

The singleturn Hiperface interface provides accurate commutation and fine position feedback per revolution with simple cabling to IndraDrive controllers. Its 128 signal periods enable granular interpolation for precise positioning without multi-turn mechanics for reducing complexity and inertia on the shaft end.

ow does a B-side power connector affect machine layout and EMC?

The B-side orientation routes motor power away from the feedback connector for simplifying harness separation for noise control. It can shorten cable runs in right-hand cable trays, improving EMI margins and easing compliance with EN 61800-3 when paired with shielded leads.

What applications best exploit the 110 Nm peak torque capability of MSK101C-0300-NN-S1-BG0-NNNN?

The short-duration peak torque benefits rapid indexing axes, press/metal-forming strokes and robotic joint acceleration. It include CNC machine tools, printing and paper handling and general robotics where fast transient moves are common.

How does the plain shaft design influence coupling and backlash management? (MSK101C-0300-NN-S1-BG0-NNNN)

The plain shaft supports backlash-free clamping or shrink-disc couplings for minimizing torsional compliance compared with keyed hubs. Its proper hub fit (H7/j6 typical) and runout control protect encoder precision during high-cycle reversals.

What maintenance considerations arise from optical encoder technology on this model? (MSK101C-0300-NN-S1-BG0-NNNN)

The optical systems provide high precision but require connector integrity and vibration control to preserve signal quality. Its housing is sealed to maintain the series’ protection and cable shielding avoids interpolation errors.
